1) You are studying a transport protein. It appears to bind temporarily to the molecule to be transported. During normal transport, no energy is expended. The addition of a particular molecule that closely resembles the normally transported molecule inhibits transport. An increase in the concentration of the normally transported molecule in the presence of a constant concentration of the inhibitor increases the rate of transport. What kind of transport is described?
2) What are peripheral membrane proteins?
In the figure below are several panels that illustrate the relative concentration of a particular solute on either side of a cell's plasma membrane. The top panel represents the INITIAL (or starting) scenario, and the lower panels represent different possible outcomes after time has passed.

- The primary function of the kidney is to exchange molecules across a membrane between the blood and the urine. One type of kidney cell has a basic rectangular shape, except for a single surface, which is lined with tiny, finger-like projections that extend into the surrounding extracellular space. Which of the following best explains the advantage these projections provide the cell? The projections increase the selectivity of the membrane because the small size of the projections limits the number of transport proteins that can be embedded in the membrane. The projections increase the volume of the cell without affecting the surface area, which increases the metabolic needs of the cell. The projections increase the surface area–to-volume ratio of the cell, which allows for more efficient nutrient exchange with the environment. The projections increase the speed at which an individual molecule can move,…arrow_forwardWhat would happen in each of the following cases where something related to intracellular transport is altered? Assume in each case that the protein involved is a soluble protein, not a membrane protein. State where each protein would be located and explain each of your answers. You add a signal sequence (for the Golgi) to the N-terminal end of a normally cytosolic protein. You change the hydrophobic amino acids in an ER signal sequence into other, hydrophobic, amino acids.arrow_forwardHow is active transport different from simple diffusion? Both active transport and simple diffusion transport molecules against the concentration gradient. In active transport, molecules are moved down the concentration gradient; on the B contrary, molecules to be transported in simple diffusion are moved against the concentration gradient. In active transport, molecules are transported with the aid of transport proteins; on the © other hand, molecules to be transported in simple diffusion do not need transport proteins. In active transport, molecules that are transported does not need metabolic energy; in contrast, molecules transported in simple diffusion need metabolic energy.arrow_forward

The concentration of water is equal in the cytoplasm of liver cells and in the blood plasma. Explain this observation in terms of membrane permeability and transport mechanisms. Animal cells typically maintain a higher concentration of Na+ outside the cell and a higher concentration of K+ inside the cell via the Na+-K+ pump. The drug ouabain inhibits the activity of the Na+-K+ pump. A nerve cell is incubated in ouabain. Predict what will happen to the concentrations of Na+ and K+ inside and outside the nerve cell as a result.arrow_forwardWhat would happen in each of the following cases where something related to intracellular transport is altered? Assume in each case that the protein involved is a soluble protein, not a membrane protein. State where each protein would be located and explain each of your answers. You change the hydrophobic amino acids in an ER signal sequence into negatively charged amino acids. You discover a protein that has both an ER signal sequence and a nuclear localization sequence. The ER signal sequence is at the N-terminus of the protein, and the nuclear localization sequence is located in the middle of the protein.arrow_forward
- The uneven distribution of ions across the plasma membrane is regulated, in part, by transport proteins. The result is a net negative charge on the inside of the plasma membrane and a net positive charge on the outside of the plasma membrane. How doyou explain the net negative charge inside the plasma membrane when the predominant intracellular ion is K+?arrow_forwardSome antibiotics act as carriers that bind an ion on one side of a membrane, diffuse through the membrane, and release the ion on the other side. The graph shows the conductance of a lipid-bilayer membrane with a carrier antibiotic as a function of temperature. Conductance 40 39 38 Temperature (°C) 37 36 What can you conclude about the effect of a carrier antibiotic on the conductance of the lipid-bilayer membrane? A carrier antibiotic decreases the conductance of a lipid bilayer, regardless of temperature. A carrier antibiotic can shuttle ions across a membrane only when the lipid bilayer is quite rigid. A carrier antibiotic increases the conductance of a lipid bilayer, regardless of temperature. O A carrier antibiotic can shuttle ions across a membrane only when the lipid bilayer is highly fluid.arrow_forwardA student designed an experiment to test whether different concentration gradients affect the rate of diffusion through dialysis tubing. Four different solutions (0% NaCl, 1% NaCl, 5% NaCl, and 10% NaCl) were tested under identical conditions. Twenty mL of each solution was placed into separate dialysis tubing that is permeable to Na+, Cl-, and water. Each bag was placed in a separate beaker and covered with distilled water. The concentration of NaCl in the water outside of each bag was measured at 40-second intervals. The graph below shows the results from the 5% bag: Concentration of NaCl Outside of Dialysis Bags Concentration of NaCl (mg/L) 400 320 240 160 80 0 40 80 Time(seconds) 120 5% Solution 160 a.
